Calling on the knowledge of any plumbers out there.
I am about to have an extension done and am looking for some guidance on whether my current boiler will be able to cope with the extra additions. I appreciate people may not be able to give me a definitive answer but something along the lines of a) definitely need bigger boiler b) may be sufficient but need plumber to do calculations and confirm c) should be ok d) more than enough
The current setup is;
3 bed semi, boiler is vaillant model no. vcw gb 242 eh, nominal input 101030 BTU(28.8KW), nominal output 81900 BTU (24KW), burner press mbar 5.1Front room 15ft by 11.9ft with standard double panel radiator Lounge 20.5ft by 11.8ft with standard double panel radiator and patio door to garden kitchen 15.5ft by 7.5ft no radiator Bedroom 1 & 2 12ft by 11ft with standard double panel radiators, Bed 3
